The SD boot loader was not satisfactory because 1) the SD slot is on an optional board and, hence, cannot be part of a fundamental solution. And 2) it is too big.
The only storage on borard is the Winbond W25 SPI-bsed FLASH. This commit adds support for a bootload to 1) read code in HEX format from a serial port and write it to the W25 FLASH, or 2) read code in binary form from the W25 FLASH into SRAM and execute the loaded program.
boards/z80/ez80/z20x/configs: Added w25boot configuration
boards/z80/ez80/z20x/src: Add bootloader logic, w25_main.c. Add logic to manage shared SRAM memory map so that the loaded program does not clobber the bootloader memory. Add logic to recover the bootloader memory into the heap after the loaded program as started.
boards/z80/ez80/z20x/scripts: Rework scripts and configuration to support a bootloader and program build. The boolloader cannot use all of SRAM; the program must not clobber the SRAM region used by the bootloader.

board/z80/ez80/*/scripts/Make.defs: Fix optimization definition use in assembly flags. It was using the compiler optimization settings instead of the assembler optimization settings. Hence, enabling optimization would could cause assembler command line errors.
arch/z80/src/ez80/Toolchain.defs: Back out some work arounds. Now compiler optimization flags can again set set without assembler command line errors.
boards/z80/ez80/z20x/README.txt: Trivial update to size/optimization discussion.
The eZ80F92 interrupt controller is very different from the eZ80F91. The eZ80F91 has:
1. Four byte interrupt vectors
2. The vector base address register is 16-bit so the vector table can lie in RAM
Whereas the eZ80F92 has:
1. Two byte interrupt vectors
2. An 8-bit vector base address
This means that the vectors must lie in the first 16-bits of FLASH and there must be a "trampoline" to get to interrupt handlers outside of the first 64-Kb of FLASH.
arch/z80/src/ez80/Toolchain.defs: Correct some CFLAGS when optimization suppressed.
arch/z80/src/ez80/Kconfig arch/z80/src/ez80/ez80_emac.c: Remove configuration option for selecting EMAC RAM address. This is duplicated and possibly conflicting. The correct address for the RAM is provided in the linker command file. The RAM should be configured once and using this single definitions.
arch/z80/src/ez80/ez80_startup.asm and arch/z80/src/ez80/ez80f9*_init.asm. Move RAM and FLAH intialization out of MCU-specific logic to common start-up logic. We cannot call any functions until SRAM is initialized and the stack is properly initialized because the return address is stored on the stack. Use internal SRAM for the IDLE stack to avoid the chicken'n'egg problem.
boards/z80/ez80/z20x/configs/sdboot/sdboot.zdsproj: Discuss build environments.
CONFIG_FAT_MAXFNAME is set to 255 and CONFIG_NAME_MAX is set to 765
which can support max file name including Japanese characters.

arch/z80/src/ez80/Toolchain.defs: Update some CFLAGS to match CFLAGS from ZDS-II IDE. Apparently, we must say that the CPU is an eZ80F91 event when compiler for eZ80F92.
boards/z80/ez80/z20x: Update linker scripts.

initial addition
* tools/zds/zds_Config.mk: Move boards/z80/ez80/scripts/eZ80_Config.mk to tools/zds/zds_Config.mk where it can be shared by other ZDS-II platforms.
* boards/z16/z16f: Duplicate changes for new ZDS-II support from ez80
* boards/z80/z8: Duplicate changes for new ZDS-II support from ez80
* arch/z16/src/z16f/Toolchain.defs: Create required Toolchain.defs file for Z16f
Eliminate the MOVEOBJ definition from tools/Config.mk, Makefiles, and other locations. The MOVEOBJ definition was used to work around the case where the object output of a compile or assemble is in a different directory than the source file. The ZDS-II tools have no command line option to perform this move; MOVEOBJ handled the move as a post-compiler operation.
MOVEOBJ is no longer needed because this the ez80 COMPILE and ASSEMBLE definitions now handle all of the object file movement cases.
tools/zds/zdsgen.c: Remove this program. It should have been a simpler way to manage ZDS-II compiler and assember differences. However, the compiler arguments needed to pass through too many layers of bash command line modifications and, as a result, it was not possible to retain quotes on critical strings. This approch was abandoned for an alternative approach.
boards/z80/ez80/scripts/eZ80_Config.mk: Add definitions to move the object files as necessary. This seems to work well and is implemented for both native and Cygwin Windows build -- but only for the Z20x.
tools/zds: A new tool sub-directory intended to hold tools for making life working with the ZDS-II toolchain less painful.
tools/zds/zdsar.c: This is a wrapper around the ZDS_II librarian. It simplifies the build scripts by replacing large sequences of complex Bash script that were added to the build files. Not only does this clean up the build files but it also improves performance and, more importantly, provides a common solution for the Windows native build case. This tool should work with all ZDS-II based platforms including z8, zNeo, and ez80.
tools/README.txt: Add a brief description about the zds sub-directory. Also re-ordered some tool descriptions. They are supposed to be in alphabetical order, but this seems to have fallen apart.
boards/z80/ez80/scripts/eZ80_Config.mk: Updated to use tools/zds/zdsar.exe.
This includes some fixes for the ez80 build including:
1. Ability to handle decorated object file names,
2. Ability to handle libraries described with absolute paths
This commit address only the POSIX build and needs to be updated
for the Windows native build.
arch/z80/arc/ez80/Toolchain.sh: Move more common toolchain definitions from Make.defs.
boards/z80/ez80/scripts/eZ80_Config.mk: Move common defines that override tools/Config.mk to this new file.
This does not solve the ez80 build problem yet but does assure that when the solution is in place, it will automatically apply to all present and future ez80 configurations.
to avoid shell complain that @echo can't find if the variable expand in the compound
command(e.g. ARLOCK) and remove $(Q) before $AR so the result is almost same as before.
Enable optimization and generate debug symbols.
Enable scheduler instrumentation and spinlock irq.
Add applications such as hello, ostest and taskset.

Update linker scripts to provide _ramfuncs sections for SAMv7 based boards. This corrects undefined reference to _ramfuncs when CONFIG_ARCH_RAMFUNCS is enabled (Issue #304)
Largely copy-and-paste from stm32f4discovery.
Also arch/arm/src/armv7-m/mpu.h: Ensure RBAR alignment
Fix crashes on init task startup I observed on qemu-system-arm -M lm3s6965evb.
Because we can get the same function by CONSOLE_SYSLOG/syslog_console_init.
BTW, it isn't a good choice to use g_ramlogfops as /dev/console since nsh
will read back what it send out which will surprise most people.
This commit adds automounter and BOARDCTRL_RESET support for SAMV71 and verified on Atmel SAMV71-XULT. Also, some fixes of Kconfig and missing uerr/uinfo definition.
To ensure size_t same as toolchain definition in the first place and rename CXX_NEWLONG to ARCH_SIZET_LONG. The change also check whether __SIZE_TYPE__ exist before CONFIG_ARCH_SIZET_LONG so our definition can align with toolchain(gcc/clang) definition automatically.
